FRANCISCO, CALIFORNIA, ASSIGNOR T0 SANITARY SCREEN OF SAN FRANCISCO, CALIFORNIA, A CORPORATIONOF CALI- WINDOW-SCREEN.

To all whom it may concern Be it known that I, ARTHUR G. Soon a citizen of the United States, residing in the city and county of San Francisco, State of California, whose post-office address is 226' Judah street, have invented new and useful Improvements in lVindow-Screens, of which the following is a specification.

The invention relates more particularly to sliding window screens adapted to close the entire window opening.

Among the objects sought to be accomplished are to eluding a plurality of sections, slidable upon each other; that is simplein construction and cheap to produce; that is easily installed within the Window opening; and that is so constructed that it maybe trimmed to fit window openings of various widths.

Other objects and advantages will appear as the description progresses.

In the drawing accompanying and forming part of the present specification, to which like reference characters have been applied, a simple form of J putting this invention into practice is shown. I do not wish to 'be understood as confining this invention to the disclosures made in said drawing and description, as many variations may be introduced, within the spirit'of this invention, as defined in the claims succeeding the said description.

The present structure is particularly adaptable to window openings fitted with pivotal or casement window sashes, in which it is often necessary to fit the screen within the opening, in the interior portion of the window frame. The construction illustrated represents a combination of frames, interconnected and slidable upon each other in such a manner, that the combined thickness of'the screen frames is kept within the limit of sightliness and the available space for installing the screen. It is important also that the screen be easily opened, giving ready access to the window sashes; and that the whole screen may be quickly and easily removed from the window frame without leaving the window opening unsightly, by reason of the nature of any permanent elements of the screen remaining, during that season of the year that window screens are unnecessary.

The particular function at Specification of Letters Patent.

such screens is to prevent the entrance of insect pests into dwellings.

In the one sheet of drawings: Figure 1 is a side elevation of a window frame in cross section, having a screen constructed 1n accordance with this invention installed therein, and shown in full'lines- Fig. 2 is a plan view from above of the screen in cross section taken on the line I III. I Fig. 3 is a fragmentary detail in front elevation of one side of the upper screen section. Fig. 4: is a side elevation of the same partially in cross section, particularly illustrating the suspending hook and the spring friction member. Fig. 5 is an enlarged detail in perspective of the upper portion of the suspending hook engaging the supporting bracket. r I

In detail the construction illustrated in the drawing includes the upper screen section, comprising a rectangular frame composed of top and bottom rails 1 and 2 joined by side stiles 3 and 4, mortised or otherwise joined at the corners to form an open frame. The opening in this, frame is covered by suitable wire mesh or screen 5, stretched across the opening and secured around the margins thereof by the top and bottom strips fi and 7 and the side strips 88. The side stiles 3 and 4 are provided with the longitudinal shallow. grooves 9-9, substantially equal in depth to the thickness of the suspending hooks 10 and the friction springs 11 fixed therein, near the top'and bottom respectively, of the upper screen section. These grooves 9 are easily and cheaply formed during the process of milling the side stiles, and serve as gains for the hooks and the friction springs into the stiles flush with the surface thereof. These friction springs are providedwith a raised portion 12, adapted to engage the contiguous portion of the adjoining screen section, to fric- 4. The side strips 8-8 are beveled ontheir outer edges to form an overhanging lip 1e. I The lower screen section consists of a reetan lar frame smnlar to the up e section 'composed at top and bottom rails is r r 65 the guide fixtures. When it is necessary to and 21 are preferably formed of hardwood, that being best adapted for the prin pose, or they may be formed of metal with the same functional characteristics. The exposed sides of the strips 20 and 21 are provided with the longitudinal grooves, coincident with the grooves 9 and into which the friction portion 12 of the springs 11 extend and exert a retarding friction, when the lower screen section 1s raised or lowered across the upper section. When the screen is fully extended, that is, when the upper rail 15 'of the lower section overlies the lower rail2 of the upper section, the maximumstrain is exerted between the overhanging edges 14 and 22 of the strips 8, 20 and 21; to relieve these guide strips from the danger of splittingfthe plates 23 are attached by the screws 24: to the side stiles 3 and 4 overlapping the strips 8 and overhanging the extended edge thereof, engaging the rabbet formed in the edge of the strips 20 and 21. These metal strips have a firm and substantial sliding engagement with the strips 20 and 21,;securely holding the upper and lower sections together, and

relieving the guide strips from undue strain.

1 Inthe drawings a screen having two sections is illustrated. It is obvious however, that a' greater number of sections could be similarly combined. The suspending hooks 10 engage the slots 25 in the brackets 26 attached to the stop 27, fixed across the top of the window opening abuttingthe closed sash. Suspended from the brackets 26 the upper section hangs against the side stops 28, securely screening the upper half of the window opening. The lower section of'the screen attachedto] the upper section as described, similarly screens the lower half of the window opening, see Fig. 1. The screen is held in this vertical position by the round headed fixtures 29, driven into the side stops'28 and engaging the grooves 30 formed in the edges of the side stiles 16 and 17 of'the lowersection; the entrance 31 to this groove is slightly fla-red to facilitate engagement with the guide fixtures. These fixtures29 are located high enough" above the' window stool 32 to'permit the raising of the lower section of the screen, for the manipulation of the lower window sash X without disengaging the lower section from manipulate the upper sash X, the lower sectiori of the screen is slid upward over. the upper section, permitting the screen to swing outward on the hooks 10, permitting a free access to the whole window opening. WVhen it is desired. to remove the screen for convenience in window washing or for any other reason, the collapsed screen is swung outward until the hooks 10 disengage from the slots in the brackets 26; the screen is restored to position by reversing this operation.

The window framing can be constructed for the reception of screens of this type by rabbeting the stops 27 28 and 38 as shown to perform the double function of acting as stops for thewindow sashes on the one edge,

and stops for the screen on the other edge.

For manufacturing reasons it is desirable to standardize the product-as much as possible, making one size of screen adaptable to as many windowwidths as may be; with this idea in view thescreen is so constructed that a considerable width can be planed off of the sidesof the screen, to fit it to a window opening narrower than the standard width of the screen; for this reason'the hooks 10 and the springs 11 are set in fromthe edge of the'side stiles. Another mode of adapting the screen to the window opening,is to provide special stops that may be trimmed down to the marginal space between the edges of the screen frames and the edges of the window opening.

It is preferable to manufacture the screen frames of woodto match the window trimmings, to maintain a uniformity in appearance; however I contemplate carrying out the functional characteristics of this invention as shown and described, in metal and do not therefore wish to belimited to the exact structure disclosed. a

1 Having thus described this invention, what I claim and desire to secure by Letters Patent is:
